' STEARNS & COMPANY, OF SAME PLACE.

FRAME-JOINT.

SPECIFICATION forming part of Letters Patent No. 590,307, datedSeptember 21, 1897. Application filed January 9, 1897. Serial 1 1 (N011106613 To all whmn it may concern:

Be it known that I, EDWIN J. FINLEY, a citizen of the United States,residing at Syracuse, in the county of Onondaga and State of New York,have invented a new and useful Frame- Joint; and I do hereby declarethat the following, in connection with the accompanying drawings, is afull, clear, and exact description of the invention.

The object of my invention is to provide a light and simple bicyclecrank-hanger and means for securely attaching the main tubes of theframe thereto. IVithin the crankhanger tube is inserted a brace or shortpiece of tubing rearwardly fitted snugly to the crank-hanger tube, butforwardly and upwardly provided with two flattened sides arrangedopposite perforations in the crankhanger tube, so as to leave a spacebetween the inner surface of the tube and said sides. The ends of theframe members inserted through said perforations fit against saidflattened sides. Corresponding smaller perforations are formed in thesesides, through which the reinforcements are inserted.

My invention will be better understood by reference to the accompanyingdrawings, in which the same numerals of reference refer to the sameparts in all the figures.

Figure I is a side elevation of my improved crank-hanger, showingportions of the frametubes and the reinforcements. Fig. II is acorresponding cross-section. Fig. III'is an enlarged elevation of theinner tube or brace detached, showing the arrangement of onereinforcement. Fig. IV is a perspective view of the brace detached.

In the various figures 1 indicates the crankhanger tube, 2 the innertube preferably cut away, as shown at '3, for lightness, fitting snuglythrough a portion of its circumference 4 to the crank-han ger tube andprovided with flattened sides 5 5, in which are the perforations 6 6 toreceive the reinforcements 7 7, provided with flanges 8 8, turnedagainst the inner face of the inner tube. The flattened sides 5 5 arearranged at the proper angle to receive against their outer faces theends of the main frame-tubes 8 8, cut square, which are inserted throughround perforations 9 9 posite the sides 5 5.

It will be seen that perforations 9 9, to which the tubes 8 8 arefitted, are larger than the perforations 6 6 for receiving thereinforcements 7 7. The parts, when assembled, are brazed securely inposition.

My crank-hanger is strong, durable, and cheap to construct. The innertube is a brace for all the parts, against which set the ends of theframe-tubes out on square, it not being necessary to mill them, as wherethey fit against a curved surface.

My crank-hanger may be entirely construct ed of simple tubes or stampedparts, and it is lighter and stronger than crank-hangers made at agreater expense from drop forgings or castings. In this construction thebrazing may be performed more eifectively and easily. The flux isintroduced at the point where the parts come together and thence flowsoutwardly around the reinforcements, an improvement on the ordinaryconstruction, in which the frame-tubes are inserted into integralnipples formed on the crank-hanger. The flux must then be introduced atthe outer edge of the nipple to flow inwardly to and around the end offrame-tube, thence outwardly.

Having thus fully described my invention, what I claim, and desire toprotect byLetters Patent, is

1. In combination with a crank-hanger tube perforated to receive themain frame mem bers, an interior tube having flattened sides oppositesaid perforations and corresponding smaller perforations in saidflattenedsides to receive the reinforcements of said main frame members.

2. In combination with a crank-hanger tube perforated to receive theends of the main post and of the lower tube of the diamond, an innertube or brace rearwardly fitted to the interior of said crank-hangertube and formed on its upper and forward portion with in thecrank-hanger tube 1, respectively op.

flattened sides, between which and the inte rior of the crank-hangertube a space is left, said flattened sides being formed withperforations opposite said perforations in the crank-hanger tube, saidlatter perforations ICQ said perforations in said inner tube and flangedon their inner ends, substantially as described and shown.

In witness whereof I have hereunto set my hand, in the presence of twoattesting wit nesses, at Syracuse,- in the county of Onondaga, in theState of New York, this 31st day 20 of December, 1896.

EDWIN J. FINLEY.
